fix -package:incipit-base -is:module package:Agda
Range of the whole fixity declaration.
Get the fixities and polarity pragmas from the current block. Doesn't
go inside modules and where blocks. The reason for this is that these
declarations have to appear at the same level (or possibly outside an
abstract or mutual block) as their target declaration.
Fixity of modules cannot be changed via renaming (since modules have
no fixity).
The notation is handled as the fixity in the renamer. Hence, they are
grouped together in this type.
Should system generated projections ProjSystem be printed
postfix (True) or prefix (False).
